AUTOMATIC HIDE-TANNING MACHINE,

Specification of Letters Patent.

Patented May 18, 1909.

Application led October 2, 1905. Serial No. 281,003.

To all whom it may concern:

Be it known that 1, CHARLES JOHN G-LAsEL, a citizen of the UnitedStates, residing at South Boston, Massachusetts, have invented new anduseful Improvements in Automatic Hide-Tanning Machines, of which thefollowing is a specification.

My invention relates to automatic hide and leather treating machines andhas for its object the novel construction and management of its partswhereby the skins or hides to be treated are manipulated, worked andcarried by rigid connections with the receptacle in combination withmoving connections which are adapted to move in radial, longitudinal orvarious directions and be contained within said receptacle but movingindependently of it. These and other details and objecps of my inventionare more fully described in the following specification and set forth inthe appended claims.

ln the drawings forming part of this speciiication and accompanyingsame, like reference characters are used to designate the same parts inthe various views.

Figure 1 is an elevation of a tanning machine embodying my invention.Fig. 2 is a longitudinal sectional view. Fig. 3 is a cross sectionalview on the line 3 3 of Fig. A2. Fig. 4 is a cross sectional view on theline Ll-Ll of Fig. 2. Fig. 5 is a fragmentary sectional detail showing amodified form of a frame. Fig. 6 is a longitudinal sectional view of themachine showing a means of mounting the skins without using frames. Fig.7 is an end view of this form of machine, Fig. 8 is a fragmentaryelevation of one of the end frames. Fig. 9 is a similar view of theintermediate frame. Fig. 10 is a view illustrating the reciprocatingmeans for the supporting roller. Fig. 1.1 is a view of a modiiicd formof supporting roller.

ln view of the well known construction and operation of these tanneryreceptacles, I have not illustrated all the details of the cylinder 5 ofthe various figures but have shown only enough to clearly illustrate myinvention.

The cylinder 5 may be of any desired construction and size, and isprovided with heads 6 and 6a and circumferential rails or hoops 7,

the latter running in the grooves of supporting and propelling rollers 8and 9 on shafts 10. These shafts are journaled in standards 11 of theconstruction shown in Fig. 1 Where it will be seen that there is somespace existing between the upright supports of each standard whichallows ample room for a longitudinal movement of each roller along itsshaft, the shaft at roller 9 being double threaded to allow of a reversemovement of the roller when it reaches the limit of its confines andstarts back in a reverse direction. The roller 9 is provided With itsnecessary interior stud 9a which plays in the reversing thread and theroller 8 is slotted at its hub to play on a spline on the shaft andfreely move longitudinally while rotating with said shaft. The roller 9is causedby the screw threads to move forward and reverse with areciprocatory motion, and the cylinder 5v is thus caused to reciprocatethrough the connection between the rails 7 and grooved wheels; therollers 8 and 9 at the same time imparting a rotary movement 'to thecylinder. The shaft 10 and its rollers are rotated by means of thepulley 12. Thus the cylinder 5 is bodily rotated and also longitudinallyreciprocated., the reciprocal movement being as great as the distancebetween the arms of standards 11. The reciprocal movement of thecylinder causes a continuous agitation of the tanning agent therein, andincreases the efficiency of the action of the agent in the process oftanning by repeatedly bringing the agent into contact with the hide witha splashing or washing effect against the hide.

In Fig. 2 it will be seen that the heads 6 and 6JL are each on theirinterior provided with rings 13 having interior 'eccentric grooves 14and within these rings are fitted coinciding disks 15 carrying a unitingshaft 16 at a point eccentric with their centers but identical withrelation to the axis of the cylinder. On the periphery of each disk is astud with roller 17 which runs in the groove 14 of the adjacent ring andcarries the disk up and down the rings interior, working in unison bymeans of the connecting shaft 16. With relation to the shaft 16, thedisks 15 are eccentrics and the shaft is of suflicient soliditl andweight to retain same below the aXis of the cylinder when it isrevolved. Upon the shaft 16 are loosely mounted frames 18 and 18a ofwheel-like construction, the end frames 18 being held againstlongitudinal movement by the collars 19 .while the intermediate frame18L is freeto rotate and slide on the shaft. The construction of theframes 18 is shown in Fig. 3, where it will'beseenthat a ring or tire 20is provided with a plurality of sockets 2.1 to vreceive the spokes v22vwhose inner ends are carried by.a hub 23, the inner side of each ringhaving hooks 24 or similar attaching means to secure parts of the hidesand hooks 25 on fthe hubs serve the same purpose at that point. Theintermediate frame .181L is vcomposed of a ring 26 and [the ring isattached to the interior of the cylinder by means of toggle arms 30 ofthin resilient material yet sufficiently substantial to afford means tocause'the yframe 18a-to 'follow the cylinder in its rotation but yieldtoany 1lateral strain put upon it from either side. This frame has hooksorclamps 31 on each side adjacent to the frames 18 and to the hooksofthe threeiframes hides are hung as shown in Fig. 2 and as the cylinder5 revolves and, lthrough the medium of the grooves '14 and rollers 17,reciprocates ythe shaft 16 andthe frames 18 yfirst toward one endandthen the other, thehides being held practically stationary by one end atthe -intermediate frame are stretched and allowed to `relax alternatelyby 'the reciprocating frames. With ythe arrangement of hooks around therings a considerable number of hides may be placed in-position andtreated. When'the treatment has been concludedthe 4ring `18aiisdisconnected from the cylinder 'by removing the ytoggle arms 30, accessbeing lhad to ythem bythe manholes 82, and by removing the head 6 andreleasing the grooved ring 13 "from the head 6u7 Vthe shaft, its framesand the hides may be taken out and ,a new supply furnished. In thetreatment of the hides'the cylinder is partly filled withcertain'liquors, air, gases, etc., well'known to Ythe art and as thedevice is actuated, the

hides are Vimmersed and carried from the liquid, the stretching andrelaxing operation continually going on to cause 4the ypores of the skinto absorb the solution which -peneyexpels vthe used solutionandleaves'thepores ready for a new or fresh supply.

:In lFig. 5 is shown a modified arrangement of one of the frames,preferably the interforth in the following claims.

mediate frame; wherein the eccentric 83 is mounted fast on the shaft 16and V'has its roller84 playin rthe grooveofthe .hub 35 of the frame 36.The shaft is in the case stationary and the frame connected by anysuitable means with Y.the .interior of the cylinder so that when thelatter' is operated the frame is rcarried `in and out of the solutionwhich is thus kept agitated, and the hides are immersed and subjected tothe `stretching action while secured to this frame and one or moreadjacent frames.

In Figs. 6 and 7 is shown a means by which the hides are stretched andrelaxed on llines radial and parallel with'the axis ofthe device whilebeing jimmersed and removed from the solution. In'this means ofaccomplishing this end l employfthe usual eccen trics 38 in thecam-groovedrings 39 and l:having the studs 40 to act inthe groove=toshift lthe eccentrics longitudinally. The eccen- Atrics are providedwith shafts or Atrurmions 4'1 one of which is provided with apulley141iL to rotate same and receives Vmotion `from a similarI pulley on theroller shaft 10. 'They are also united by a shaft 42 on alineintersecting the axis of the cylinder and provided Vwith several loosesleeves 48 which carry )oints7 4hooks or clamps 44 to Asecure the lhides-whose other ends are attached ltothe interior of the cylinder byhookssimilar to 44. This arrangement provides yfor the -radial action on thehides to amore or VAless degree as 'the center of the cylinder 'is'receded from and provides for the treatment of 'hides of differentsizes andquality. The hides are'in this case subjected to stretching andcontracting manipulations on various angular lines between vthe point aand l'the points?) and c,infFi g. 6 as the reccentrics"3 -8 Vare shiftedto lthe'left hand end o'ffthecylinder and as the shaft 42 movesaround-and upward at the same end of the cylinder, 'the strain betweenthe points a andb,and c and d, increases and the reverse movement of11,0 vthe parts produce relaxation 4in the hide l:between these points,and as the eccentrics 88 4reverse their movement the strain is from `the`point d.

4In Fig. 11 is shown an eccentric support- 115 ing roller 46 whichmay beutiliZedto-produce a vertical ymovement ofthe cylinder when used inpairs on each side of thevapparatus, or when'used on one shaft only mayproduce a movement about the shaft withordinary 120 rollers. Withthemanagement offthe'frames as shown in Figs. 3 and 4, a clear and openspace isleft in the upperpart of this cylinder which affords abundantroom for the accommodation of thehides.
